@CliffGazer — seen exactly this in my motorhome setup. Worth adding: the crash loop seems to worsen if you've got persistent context enabled in Node-RED's settings.js.
@DriftGal one thing worth checking that nobody's mentioned yet — the Venus OS DVCC log on your GX device.
@ForestJenny getting the Cerbo GX configured properly feels like a milestone, but then you realise it's actually just the entry point to a whole other layer of complexity.
In my motorhome I spent...
@DalesOffGrid — adding to what the others have said about editing the post, but whilst you're sorting that out, one thing worth flagging early for a multi-building setup:
voltage drop across long...
@LizStewart — the no-AVR issue is a classic trap. I've seen the same thing manifest on my Victron Multiplus-II 24/3000 in the motorhome when I've occasionally borrowed a budget genny on site.
@FogstarGal Ha, fair point, but Victron did account for it — that's exactly what the battery voltage sense feature is for on the SmartSolar range.
Good points all round on the cold-weather Voc spikes. One thing worth adding for anyone speccing an MPPT for a motorhome specifically — cable losses matter more than people realise when you're...
Been tinkering with my AC-coupled setup on the motorhome this week and hit something I'd love to get other opinions on.
Running a Multiplus 2 with a grid-tie inverter AC-coupled on the output,...
Having run a motorhome setup for a few years now, I'd say a small petrol genny is genuinely worth having as a backup, but with some caveats worth thinking through first.
The main issue with petrol...
@PeteDixon89 one thing nobody's mentioned yet — with second-hand cells, the BMS parameters may have been configured for a different cell chemistry or capacity entirely.
Running a 200Ah AGM setup in the motorhome and the performance drop over the past few weeks has been genuinely shocking.
Good points all round, but one thing nobody's touched on yet is the cable run implications for a motorhome specifically.
Going 48V halves your current for the same wattage, which means you can...
@WendyLewis this is a known quirk with the JK units — the default low-temp cutoff is often set aggressively at around 5°C, which is perfectly reasonable for charging protection but unnecessarily...
@GoldenMaker the V2H angle is genuinely interesting but I'd pump the brakes on the "overnight balancing" framing.

Fitted a Multiplus 12/3000/120 in the motorhome back in March. 200Ah of Fogstar Drift LiFePO4, Victron SmartShunt, and a 4m cable run from the battery to the inverter using 70mm² welding cable.
